The BRICS are working out a currency plan that requires local currencies to be backed by a mix of 40% gold and 60% other assets. The higher the price of gold the better for them. That will also take PM's off the market as they'll need to be held in reserve.
Random thoughts:
I don't think the BRICS requirement is for local currencies to be backed by 40% Gold and 60% other assets, but for the BRICS "UNIT" currency to be backed by that asset allocation. In any case, I don't think it will work.
Whether you define Gold as money or as a commodity, it's very easy to attach it to a convertible currency, as the United States did prior to 1933. If you had a $10 bill, you could walk into any bank and exchange it for a $10 gold piece or vice-versa. The UNIT can't really be a convertible currency, as it's currently described. Do you walk into a bank and come out with some gold and a certain amount of grain and crude oil?
Of course I understand that the UNIT is designed to facilitate trade between countries and not individuals, but I think the commodity component needlessly complicates things. Commodities are valuable in and of themselves, but different countries have different needs and the value of commodities are constantly changing. Saudi Arabia probably doesn't want crude oil, but they could probably use grain.
All of those trades could more easily be made with Gold alone: So many tons of corn are worth so many ounces of Gold. There is, as I see it, no need to complicate things with a commodity peg.
Regarding cryptos, I confess nearly complete ignorance, however my gut feeling aligns with Bill Holter's description of them as "digital air." More importantly though, I believe we are entering an era where we will want to eliminate any middle man between ourselves and our wealth. Do understand that I do (of course) have bank accounts and I actually maintain a (modest) stock brokerage account; I don't exactly live in a cave. On the other hand, those are a small portion of my net worth.
I can't access my assets in either the bank or my brokerage account without the assistance of those institutions. Should either fail, I'm left out in the cold, for a possibly protracted period. On the other hand, I can actually touch and immediately access the Gold, Silver and cash I keep in my own possession: No middle man! I understand that the vast majority of crypto holders are using exchanges to transact and hold their coins. The Mt. Gox and other exchange implosions leave me skeptical of them. I want the majority of my assets in hand and immediately accessible.
As we move further into an increasingly unstable future, I believe it's all the more important to eliminate any second or third parties between ourselves and our wealth. No middle man!
